GRAVITY-HINGE.

Patented July 30,1912.

Appliation filed June 15, 1911. Serial No. 633,310.'

13e 'l known that I, SIGMUND Finir, a subject of the King ot' Hungary, residing at San Diego, in the county ot' San Diego and State ot' California, have invented certain new and useful lmproven'icnts in Gravity- Hinges; and l do declare the following to be a, full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. b l

This invention relates to improvements in gravity hinges.

Une object ot' the invention is to provide a hinge having an improved construction and arrangement oiE operating devices whereby when the door to which the hinge is connected -is swung open to about right angles, the same will remain in this position until started back whereupon the operating devices' oit the hinge will beactuated by gravity or the weight of the door to completely close the same.

`With this and other objects in view, the invention consists ot certain novel features of construction, combination and arrangement ot parts as will be more fully described and particularly pointed out in the api'iended claim;

in the act-onuianying drawings: `Figure 1 is a plan vieu' of my improved hinge showing the ponilion'ut the parts when thehinge open; liig. 2 is a similar view showing thehinge closed; Fig. l is a rear edge view ot the hinge cli-sed as shown in Fig. Q; Fig. -t is a crm-is sectional view on the line l---4 oi Fig. l Fig. 5 is a plan view of the hinge menibeue with the pintle ard operating members removed; Fig. (S is a perspective view ol' one ot the hinge operating devices removed; Fig. 7 is a similar View of the other leaf operating device; Fig. is a iew similar to Fig 3 with parts ln'oken away and in section showing a modified arrangement ot the hinge operating devices.

My in'iproved hinge comprises members 1 and 2, in the term ot ilat leaves or plates. The plate or leat' 1 has formed on its inner edge a vertical knuckle 3 below which is l'ormed an elongated lug 4. At the lower end of the lug the edge of the plate has loi-med therein a shallow reces l5. I

The member 2 has formed on its inner edge near its upper end a short vertical knuckle f5 and near its lower end a longer slightly modified form of the hinge.

knuckle 7. -Abo've the knuckle 7 is formed an elongated lug 8v and abov'esaid'lug is formed a shallow recess 9.

Engaged with the knuckles 3, 6 and 7 of th'e hinge members is a pintle or hinge pin 10 rhaving reduced threaded ends 11 on which are screwed knobs or heads 12. On the pin or pintle 10 and engaging the recesses 5 and 9 are lower and upper collars.

3 and 14 which have the opposite sides of their engaging ends cutaway to form cam or inclined surfaces 15 and 16 which are adapted to engage when the hinge is opened or closed. When the door is opened to a position at right angles to its casing and the hinge members brought in line with each other the 4inclined surface oi the collar 14 on the door member of the hinge will have ridden up the inclined surface of the collar of the frame member of the hinge and the flat surfaces ot' the collars thus brought into engagement whereupon the door will rcmain open until swung back 'far enough to.

again bring the inclined surfaces int-o engagement. lVhen thus engaged, the weightof the door will force the inclined surface ot the collar of the door member oif the hinge to slide down the inclined surface of the co-acting collar of the frame member, thereby swinging the door to a closed position.

The collars \13 and let have formed in one side thereof vertical slots 17 with which the lugs l and S of the hinge members or leaves are adapted to be engaged, whereby said collars` are turned by the hinge members to bring the inclined surfaces of the collars into and out of engagement. I. ln Fig.' 8 of the drawings is shown In this 'Form the collars 13 and 14 are shown to be counter-bored in their outer endsto form sockets 1S whereby the eyes-or loops of the hinge members are adapted to set into the sockets 1S. This construction and arrangement braces the parts and is intended more particularly for large heavy hinges. From the foregoing description taken in connection with the accompanying drawings, the construction and operationof the invention will be. readily understood without requiring a. more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without depart-ing from the principle or sacrificing any of the advantages of the invention as defined in the appended claim.

Having thus described my invention what Iclaimis: l' A hinge comprising door and frame mem'- bers having cooperating knuckles on their adjacent edges, a pintle adapted for insertion in said knuckles to hingedly 'and slid- .ably connect said members, lugs on the optposed Aedges of said hinge members ar- Y ranged in different planes, collars pivotally my hand in presence of two subscribing Wltnesses.
